Resumen:
Objective: The purpose of the study was to identify dental fluorosis
prevalence and to analyze its association with tap water fluoride
concentration and beverage consumption in school children from the city
of Oaxaca, who were receiving fluoridated salt. Study design: A
cross-sectional study was performed on elementary public school
children. Dean's Index was applied to assess dental fluorosis. The
parents of the children who were studied completed a questionnaire about
socio-demographic characteristics and type of beverages consumed by
their children. A total of 917 school children participated in this
study. Results: Dental fluorosis prevalence was 80.8%. The most
frequent fluorosis category was very mild (41.0%), and 16.4% of the
children were in the mild category. The mean water fluoride
concentration was 0.43 ppm (+/- 0.12). No association was detected
between tap water fluoride concentration and fluorosis severity. The
multinomial regression model showed an association among the mild
fluorosis category and age (OR = 1.25, [95%CI 1.04, 1.501) and better
socio-economic status (OR = 1.78, [95%CI 1.21, 2.601), controlling
for fluoride concentration in water Moderate and severe fluorosis were
associated with soft drink consumption (OR = 2.26, [95%IC 1.01,
5.09]), controlling for age, socio-economic status, and water fluoride
concentration. Conclusions: The prevalence of fluorosis was high. Mild
fluorosis was associated with higher socio-economic status, while higher
fluorosis severity was associated with soft drink consumption.
